Answer:
6.6242 x 10 ^ 24
Explanation:
This is the correct answer because you know there is 11 oxygen moles in 1 mole of sugar so using dimensional analysis you can solve it. You start will 11 moles of oxygen, and multiply by Avogadro's number(6.022 x 10 ^23) to get the amount of atoms. I don't see it as an answer, but I am confident in this, so I would ask your teacher specifically.
Hope this helps!

Why does all matter contain thermal
energy?
A. Because particles stop moving
B. Because all matter is hot
C. Because particles can never stop moving
D. Because all matter is cold
Answer:
The answer is C. Because particles can never stop moving
Explanation:
"All matter has thermal energy, even matter that feels cold. That's because the particles of all matter are in constant motion and have kinetic energy."

28) what is the number of oxygen atoms in the formula unit of Ca3(PO4)2?
Answer:
4.816x10²⁴atoms
Explanation:
the number of moles of oxygen is 8
let x be number of oxygen atoms
recall that 1 mole=6.02x10^23 atoms
therefore, 8 moles =x
cross multiply
8 x 6.02 x 10^23 = x
x = 4.816 x 10²⁴atoms

You know that a circuit is a path along which electrical charges can flow. In this activity, you are going to illustrate that the flow of electricity needs a closed circuit. Your task is draw the wires that connect these objects in order to create a closed circuit. In the space provided, write one sentence that identifies why this circuit allows electrical charges to flow. Be sure to include each object in your answer.
Answer:
I cant do it for you but to help you I can tell you this The charged particles can move only when there is a complete conducting pathway (called a 'circuit' or 'loop') from one terminal of the battery to the other.
Explanation:
How did the Heisenberg uncertainty principle contribute to the idea that electrons occupy “clouds," or "orbitals”?
Answer:
Because the exact position of the electron is not known,it must be assumed that the electron takes up the entire space in an orbital.

How do characteristic properties help you determine whether a chemical
change or a physical change has occurred? I
Answer: The difference between a physical reaction and a chemical reaction is composition. In a chemical reaction, there is a change in the composition of the substances in question; in a physical change there is a difference in the appearance, smell, or simple display of a sample of matter without a change in composition.

pls help me out!! perform the mathematical operation and report to the appropriate number of significant figures 0.00325136-1.76527
Answer:
-1.76202
Explanation: Because the operation is subtraction, you would count the number of digits after the decimal point. Then you would perform the operation and round your answer to the SMALLER number of digits after the decimal point.

Answer: It is conserved.
Explanation: When the box is pushed across the floor, then floor and box becomes warm which resembles the condition of conservation of energy.
The given problem can be resolved by the concept of energy conservation. The statement of energy conservation says that, "Energy is neither be created nor be destroyed, but it is converted from one form to another.
In the given problem, the person pushes the box across the floor, such that the mechanical energy from the moving arms of person is transferred to the box, and the box and floor becomes warm.
During this process, the energy from the person moving arm is transferred to the box in the form of kinetic energy. And thus kinetic energy is then being transferred to thermal energy or heat energy, due to which the box and floor becomes warm.
Thus, we can conclude that the given case reflects the process of transformation of energy from one state to another, which highlights that during the process, energy is conserved.
